AI Technical Summary

Benefits of technology

The present invention provides a marking instrument that has two marking portions: one for dispensing erasable ink and another for dispensing non-erasable ink. This allows for the use of different types of ink for different purposes. Additionally, the invention provides a system that includes both a marking instrument and an eradicating instrument for easy clean-up. The invention also includes a kit with multiple marking instruments and an eradinating instrument, as well as instructions for use. Essentially, the invention provides more flexibility and convenience for users by allowing for the use of different types of ink and convenient clean-up.

Problems solved by technology

However, a disadvantage of non-erasable markers is that the markings cannot easily be erased and / or corrected.
In addition, commercially available editing / correction tools do not include a combination of erasable and non-erasable inks in a single instrument, requiring the user to search for, find and retrieve separate marking instruments to write over erased text.

example 1

[0061]Six drawdowns were prepared—three being an erasable black ink and three being a non-erasable black ink. Delta E* for each of the drawdowns were measured. The Delta E* value for the three erasable black inks were averaged together and the Delta E* for the three non-erasable black inks were averaged together. The resulting Delta E* values of the erasable and non-erasable inks are presented below in Table 1:

Abstract

Described herein are marking instruments comprising an erasable ink and a non-erasable ink; eradicating instruments; and systems comprising same.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application No. 62 / 037,161, filed on Aug. 14, 2014. The disclosure of the above application is incorporated herein by reference.BACKGROUND[0002]Non-erasable markers are typically used in home, classroom or office environments for various marking purposes. Non-erasable markers allow a user to mark indicia on various substrates without the risk of the markings being smudged or accidentally erased. Non-erasable markers can also be used to mark on various items which cannot be written upon by other writing instruments.[0003]Non-erasable markers may be advantageous in that the risk of smudging the markings is minimized once the ink has dried, thereby minimizing the risk of transference of ink to items and persons that come into contact with the markings. However, a disadvantage of non-erasable markers is that the markings cannot easily be erased and / or corrected. In addition, commercially...
